A student management method based on a cloud platform is applied to the student management system based on the cloud platform.
EXAMPLE III
The present embodiment is different from the second embodiment in that: as shown in fig. 2, the cloud platform further includes an information comparison module, a seat marking module, an information statistics module, and an area marking module.
The APP terminal is also used for sending student information of the login APP input by the students to the cloud platform.
The information comparison module is used for receiving the student information, screening out the face information of the login student from the student information, comparing the face information of the login student with the face information of the abnormal student, marking the corresponding student information of the face information of the login student and the face information of the abnormal student as abnormal course replacing conditions when the face information of the login student and the face information of the abnormal student are inconsistent, and feeding back the abnormal course replacing conditions to the teacher through the information pushing module.
And the seat marking module is used for receiving the abnormal coordinates, acquiring a full school classroom distribution map from the database, marking abnormal classrooms in the full school classroom distribution map according to the abnormal coordinates, and counting the abnormal coordinates according to the abnormal classrooms to generate an abnormal probability seat table. For example, the abnormal coordinates are 10 in total, 9 of which are the same coordinates, the abnormal probability of the coordinates is 90%, the abnormal probability of the other coordinates is 10%, and the abnormal probability of the two coordinates is marked in the seat distribution of the abnormal classroom, that is, the abnormal probability seat table is generated.
The seat marking module is further used for sequentially acquiring the abnormal probability of each area (namely each coordinate) in the abnormal probability seat table, judging whether the abnormal probability is greater than the preset abnormal probability, if so, marking the area corresponding to the abnormal probability as the abnormal area, otherwise, not marking, continuing to judge the abnormal probability of the next area, and after marking is finished, feeding back the marked abnormal probability seat table to a teacher through the information pushing module.
And the information counting module is used for counting the times marked as abnormal student information to generate the abnormal probability of each student and storing the abnormal probability of each student in the student information.
And the area marking module is used for generating an effective check-in area and an ineffective check-in area (the abnormal area is the ineffective check-in area, and the rest unmarked areas are the effective check-in areas) according to the marked abnormal probability seat table, and storing the effective check-in area and the ineffective check-in area.
The attendance module is also used for the APP terminal and links when the terminal is established with the information link, acquires student's unusual probability according to student's information, when student's unusual probability is greater than and predetermines the probability of registering, acquires the region of effectively registering and invalid region of registering, predetermines the probability of registering and predetermines for school predetermines in advance. When the positioning coordinates are located in the range of the effective check-in area, a link is established with the cloud platform; when the positioning coordinates are located in the range of the invalid check-in area, the APP terminal cannot establish a link with the cloud platform.
